Participants

Reaction Steps

400 mg of (2S)-2-amino-N-{4-[3-chloro-4-(pyridin-2-ylmethoxy)-phenylamino]-7-(3-methoxypropoxy)-quinazolin-6-yl}-propionamide as a starting material was dissolved in 10 ml of THF and 3 ml of water, and reacted with 0.07 ml of acryloylchloride at room temperature for 1.5 hours after adding 188 mg of sodium bicarbonate. The reacted solution was extracted with a mixture of chloroform and isopropanol after adding water, washed with water and saturated saline solution, dried over anhydrous sodium sulfate, filtered and distilled under a reduced pressure, and the resulting residue was subjected to column chromatography (eluent-ethylacetate:methanol=15:1) to obtain the title compound (110 mg, 25%).
